What PT and AEDT Actually Are
PT — Pacific Time
Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST.
Pacific Time anchors the US technology industry, so a great deal of software and scheduling convention is written implicitly around it.
AEDT — Australian Eastern Daylight Time
Sydney, Melbourne, Canberra, Hobart from October to April. Standing at UTC+11:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, April 4, 2027, to AEST. Brisbane and the rest of Queensland stay on AEST year-round, so they fall an hour behind Sydney each summer.
AEDT is the southern summer half of Eastern Australia, running roughly October to April — the opposite half of the year from northern hemisphere daylight time.
What This Means in Practice
The date changes mid-working-day
For 8 of the eight hours in a normal PT working day, the equivalent AEDT time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
Both sides change clocks, on different dates
Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.
Nearly opposite sides of the clock
At 18 hours apart, one side's morning is the other side's night. Handing work over at the end of a shift usually beats trying to get both parties in the same call.
